Urban Forest Symposium

Urban Forest SymposiumComing up on Monday, May 15, from 8 a.m. to 4:30 p.m., the University of Washington Botanic Gardens (UWBG) and PlantAmnesty will be hosting the 5th Annual Urban Forest Symposium. Held at the Center for Urban Horticulture, this year’s symposium will focus on the theme of “Trees and Views,” a contentious issue that often pits view seekers against tree lovers.

Sessions range from “The Aesthetics of Views” to “Views and Laws” to “Trees, Views and Slope Stability.” The symposium draws on a host of experts and practitioners in the field, and topics target a wide range of interested parties, including arborists, attorneys, municipalities, planners, developers, tree advocates and HOAs.

Check out the full program!

Registration is $75 per person, and lunches are available for $15 (or free for the first 100 registrants). A limited number of seats are still available, and lunch ordering will be available until Wednesday, May 8.

Celebrate Earth Day at the Arboretum!

This Saturday, April 13, from 9 a.m. to 2 p.m., roll up your sleeves and come join the Student Conservation Association (SCA), the University of Washington Botanic Gardens (UWBG) and Seattle Parks and Recreation for a day of fun service projects to help improve the Washington Park Arboretum!

Organizers have selected about eight work sites throughout the Arboretum. Projects range from weeding and invasive plant removal to mulching and even some trail work, with different tasks suitable for 8-year-olds up through early teens and adults.

Earth Day 2012

2012 Earth Day volunteers. See how pumped up and excited they are?

This year’s service event is expected to draw some 300 volunteers, including a crew from a fraternity and sorority at the University of Washington, groups from Southwest Airlines and other corporate partners, volunteers from the National Park Service, local high schools and other individual participants.

The event officially kicks at 9:30 a.m. with introductory remarks from several speakers, including Tom DeLuca, director of the School of Environmental and Forest Sciences. By 10 a.m., volunteers will begin fanning out to project sites around the Arboretum, and the event ends at 2 p.m.

If this is the first you’ve heard of the clean-up, don’t worry, it’s not too late to sign up! You can register online up until noon on Friday, April 12, and walk-up registration on Saturday will be available beginning at 9 a.m. They’re eager for all the hands they can get, so come spend a morning playing in the dirt, celebrating our Earth, working together to beautify our community, and getting youth and community members involved!

Where: Washington Park Arboretum, 2300 Arboretum Drive E, Seattle 98112. We will meet in the Meadow, which is about a five-minute walk south of the Graham Visitors Center on Arboretum Drive.

What to bring: Water bottle, sack lunch, travel mug for a hot drink, sunscreen, rain gear, long pants, layers of clothing and boots. (Some snacks and drinks are provided.)

What you won’t need: Tools, gloves, environmental education and project materials, all of which will be provided on site!

For more info or to register, visit the SCA’s event site, email wanw@thesca.org or call 206.324.4649.

This May, the Blitz is On at the Arboretum!

BioBlitz

BioBlitzers come across all sorts of animals, including owls and beavers, as well as more slithery critters.

If you love surveying local flora and fauna, and testing your identification skills in the field, then mark your calendars for May 10 and 11, 2013, when the UW Botanic Gardens will be hosting its third BioBlitz at the Washington Park Arboretum!

A BioBlitz, for the uninitiated, is a biological inventory that takes place over a short period of time, and in a specific location—in this case, the Arboretum. The purpose of a BioBlitz is to take a snapshot of biodiversity as a way to measure the health of an ecosystem. The more organisms found, the healthier the ecosystem.

For the UWBG, the BioBlitz is an important tool to help manage their site as sustainably as possible. It’s also a great way to connect the UW academic community with the general Seattle community, and in the process, raise awareness of the importance of biodiversity, including in urban environments. And for those who participate, a BioBlitz is hands-on and fast-paced, and a lot of fun, says Patrick Mulligan, UWBG education supervisor at the Washington Park Arboretum.

BioBlitz

Mushrooms galore!

The way it works is that small groups of citizen scientists and UW students head out with a team leader—GPS/data collector and notebooks in hand—for 2.5-hour shifts in search of various taxa (birds, bugs, fungi, plants, etc.). As a team, they try to ID and count what they find, and record the location where they found it; in some hard-to-identify cases (e.g. fungi, insects), specimens are collected to be keyed out and identified later.

Sound like fun? Mulligan is still looking for taxa team leaders! Whether you’re a graduate or undergraduate student, TA or RA, professor or professional scientist, there are lots of ways to get involved. Each team has room for eight participants, and there are several shifts each day, so contact Mulligan for more specific information.

One year, BioBlitzers found a potentially new species of spider. This year, what might you find?

Arboretum History, Maps Going Digital

Grid Map

Since it opened in 1934, the Washington Park Arboretum has hosted thousands of plant collections and species, each with a meticulously kept record and history. Until recently, many of those details from 1934 through the 1980s—when the database became digital—have been preserved solely on paper, scribbled on grid maps or filed in countless handwritten notes.

This past August, though, the University of Washington Botanic Gardens (UWBG) received a grant from the Institute for Museum and Library Services to begin digitizing those records and create an interactive Geographic Information Systems (GIS) map for the entire park. In the end, planners and visitors will be able to go online and pinpoint specific plants and collections within the arboretum, and access all sorts of historical details—a prospect that has everyone at UWBG and the arboretum buzzing.

“People will be able to find an area in the Arboretum, then zoom down and see which plants are there,” says Tracy Mehlin, project manager and information technology librarian at the Center for Urban Horticulture. “It will be really fascinating and educational to have all of that history linked to the plant records, and accessible online to everyone.”

Grid Map

One of the first tasks of the project was to begin surveying and verifying the geospatial coordinates of the 230-acre park, which decades ago was originally divided into 595 grid squares, each 100 feet by 100 feet. When those grid markers and coordinates are confirmed, they will be used to create a map that supports the geo-referenced database. Two- and three-person teams of students and staff have already been out surveying for the past couple months.

It’s a multi-tiered project, and Mehlin has been working closely with other partners at the School of Environmental and Forest Sciences (SEFS).

Sarah Reichard, director of UWBG, is the principal investigator on the grant along with Soo-Hyung Kim, a professor of plant ecophysiology. Jim Lutz, a research scientist and engineer with the College of the Environment, has been helping coordinate the student survey crews and GIS mapping, and David Campbell is working on the searchable database and Web interface. Others involved are helping with various projects, including digitizing the existing maps, as well as handwritten notes and histories attached to each of the park’s 10,000 accessions (plants specifically added and catalogued as part of the arboretum’s collections).When completed, the searchable database will be a boon for environmental research and park management. It will also expand interpretative opportunities for visitors.

“The really fun part of it starts when it’s done,” says Reichard. “The idea is that eventually you’d be able to get the coordinates of a particular collection, like our magnolias, and locate them on your cell phone or GPS unit. We can start putting together virtual tours, and visitors can go from plant to plant.”

The grant covers two years and is expected to run through August 2014. By then, anyone with a Web-connected device will have unprecedented access to most of the living collections—barring a few rare species—at the arboretum. And for the rest, you’ll just have to come out and explore the park on foot!
